menses.

To all whom. it may concern:

Be it known that I, RAYMOND 13. PRICE a residing in the boroughof Manhattan,

useful Improvements in the Treatment of Materials and Articles Produced Thereby,

ofwhich the following isa specification.

. My invention relates to the treatment of fiber, strands, threads, cords or cables and the like, and has for its main object to provide an improved method of coating and treating thesame whereby they will more retain said coating when utilized perfectly to be twisted into into fabric.

My invention also embodies certain. modlarger elements or woven In the treatment of fiber, strands, threads, cords, cablesand the like wherein they are coated with rubber or similar substances for the pur use of strengthening as well as waterproo ng the. same it has been found that,

= when so coated, and afterward twisted into sld elements of larger dimension and then. cured, by reason of their shrinkage and tendency to untwist, particularly under the vul-A canizlng heat, the coatingon the adjacent.

surfaces of the coated elements becomes forced out, leaving their adjacent surfaces contacting, as is the case .when they are coated or otherwise treated subsequent to bein twisted. 4

l/ly present invention is intended to effactually revent this forcing out of the coating, w ich I accomplish by either partially or completely curing the elements so a coated beforeithey elements.

are twisted into larger And said cure may be an one of r the well known cures, such as co d cure,

mold cure, hot air cure, and the like.

I have also found that when the strands, threads or cords so coated andcu'red are woven into fabric they are similarly benefited. by reason of the. fact thatjeven'. under strain, the fabric willas' to its component elements retain the coatings intact therwn.

It will be obvious that thegfiber, strands, threads, cords or cables may be filled with a lubricant, such as .oil, wax, tar and the like before. the coatin is applied. and a mi also be apparent t at any anti-sticking substance may be applied to the coated elements itely pointed out with t Specification of Letters Patent.

g snares rnrnnr orricn before being further utilizedfif desired.

Furthermore, the coating may be of any desired shape, such as round, oblong or the twisted Fig. 3 is a perspective view showing a section severed on the line 3.3,Fig. .1, and twisted; I I

Fig. 4 is a fragmentary view of a fabric embodying my improvements. I

My present invention contemplates em-' bedding fiber, strands, threads, cords or ca bles in parallel relation in a plastic base, such as rubber, w hich ma be as thin or as thick as desired, as shown in Fig. 1, and then twisting sections of said base cut parallel line of the material embedded therein into strands, threads} cords or cables, as shown in Figs. 2 and the same beill in either partially or wholl cured, as by su jecting the same preferably to heat at or above the temperature of the melting point of sulfur, that is, 238 F., and below the temperature of the extreme fluidity of sulfur, that is, 248 F. Between these temperatures vulcanization takes place in the rubber. However, the temperature may be carried up as highas 290, which is the highest that can ordinarily be used for vulcanizing without burning or ,carbonizing the rubber. This heating treatment is continued for a period sufficient to produce the desired degree of vulcanization in the rubber and to produce the best results, it is essentlal that this heatin step be erformedprior to said twisting. d it W1 1 be obvious that from such elements so formed larger elements may be built up by twisting a lur'alit of the same'together to a size suita le to. orm

' sections as above and twist the same into a larger element, or I may twist one or more of said sections around a rubber core itself either raw or partially or wholly precured but ordinarily, twisting a section in a sh ht spiral, as shown in Fig. 3, causes the rub er coating on the inner faces to cohere and form a rubber core. It will be obvious that the same.

ter ma .only may any form of rubber beused for this purpose, but that such substances as guttia percha, balata-and the like may be. use 7 Obviously, the flexibility and extensibility of the articles produced can be regulated and. proportioned bythe amountofjcoating' as well as by the weave, knit, braid or twist of the same.

It also contemplate combining fibers, strands, threads, cords or cables and the like so treated withother fibers, strands, threads, cords or cables and the like that are 1111- coated. Or I may coat and cure, either' partially or wholly, certain fibers, strands, thread-s, cords or cables and the like, and then combine the same with other fibers, strands, threads, cords, cables and the like that are coated but uncured, and then (sure And in this connection I contemplate combining different characters of materials, such as rubber threads and the like, or metal threads with fibers either uncoated or coated as hereinbefore described and cured either before or after being so combined. :In fact, a wide variety of comb natlons is obv ously possible, involving materials of various characters with fibers so coated. f

- memes I In an application for Letters Patent filed by me January 19, 1912, Serial No. 672,261, -I have disclosed certain processes of treating fibers, strands, threads and tl% like, the same inv0lving, am0ng others, the use of a vacuum to cause a more thorough permeation of the material being treated by the strengthening and waterproofing medium, as well as the use of pressure rolls, either with or Without the. vacuum, and it will be understood that I contemplate the use of ments, twisting said elements to produce an element of larger dimension, building said element into an article of manufacture, and

finally curing said element.

In testimony whereof K have hereunto set my hand in the presence of. two subscribing witnesses;
